| 2 | Spectroscopy,decay properties and Regge trajectories of the B and B_s mesons显示文摘A Gaussian wave function is used for detailed study of the mass spectra of the B and BS mesons using a Cornell potential incorporated with a O(1/m) correction in the potential energy term and expansion of the kinetic energy term up to O p^(10) for relativistic correction of the Hamiltonian.The predicted excited states for the B and B_s mesons are in very good agreement with results obtained by experiment.We assign B_2(5747) and B_(s2()5840) as the 1~3P^2 state,B1(5721) and Bs1(5830) as the 1P_1 state,B0(5732) as the 1~3P_0 state,B_(s1)(5850) as the 1~P 1 state and B(5970) as the 2~3S_1 state.We investigate the Regge trajectories in the(J,M^2) and(nr,M^2) planes with their corresponding parameters.The branching ratios for leptonic and radiative-leptonic decays are estimated for the B and BS mesons.Our results are in good agreement with experimental observations as well as outcomes of other theoretical models. | Virendrasinh Kher Nayneshkumar Devlani Ajay Kumar Rai | 2017 | Chinese Physics C2017，41，9： | 0 |
| 3 | Mass spectra and Regge trajectories of Λ_c^+,∑_c^0,Ξ_c^0 and Ω_c^0 baryons显示文摘We calculate the mass spectra of the singly charmed baryons(A_c^+,∑_c^0,Ξ_c^0 and Ω_c^0) using the hypercentral constituent quark model(hCQM).The hyper color Coulomb plus linear potential is used to calculate the masses of positive(up to J^p=7^+/2) and negative(up to J^p=9^-/2) parity excited states.The spin-spin,spin-orbital and tensor interaction terms are also incorporated for mass spectra.We have compared our results with other theoretical and lattice QCD predictions for each baryon.Moreover,the known experimental results are also reasonably close to our predicted masses.By using the radial and orbital excitation,we construct Regge trajectories for the baryons in the(n,M^2) plane and find their slopes and intercepts.Other properties of these baryons,like magnetic moments,radiative transitions and radiative decay widths,are also calculated successfully. | Zalak Shah Kaushal Thakkar Ajay Kumar Rai P.

| 10 | Excited state mass spectra, decay properties and Regge trajectories of charm and charm-strange mesons显示文摘The framework of a phenomenological quark-antiquark potential(Coulomb plus linear confinement)model with a Gaussian wave function is used for detailed study of masses of the ground, orbitally and radially excited states of heavy-light Qq,(Q=c,q=u/d,s) mesons. We incorporate a O(1/m) correction to the potential energy term and relativistic corrections to the kinetic energy term of the Hamiltonian. The spin-hyperfine, spin-orbit and tensor interactions incorporating the effect of mixing are employed to obtain the pseudoscalar, vector, radially and orbitally excited state meson masses. The Regge trajectories in the(J,M^2) and(nr,M^2) planes for heavy-light mesons are investigated with their corresponding parameters. Leptonic and radiative leptonic decay widths and corresponding branching ratios are computed. The mixing parameters are also estimated. Our predictions are in good agreement with experimental results as well as lattice and other theoretical models. | Virendrasinh Kher Nayneshkumar Devlani Ajay Kumar Rai | 2017 | Chinese Physics C2017，41，7： | 0 |
